The military for years has enlisted anthropologists, depending on their expertise to write up analyses of distant places and cultures. But debate is growing among those scientists over whether it is appropriate for them to be involved in actually working alongside soldiers in combat or to contribute to the growing field of counterterrorism research.

Defense Secretary Robert Gates on Friday welcomed David Petraeus as the new chief of Central Command with responsibility for America's two wars, saying he hopes the general will help bring needed coherence to the U.S. and allied strategy in an increasingly volatile Afghanistan.

Gen. David Petraeus, who was credited with leading a successful counterinsurgency strategy that pulled Iraq from the brink of civil war in 2007, said bringing stability to the broader region will require harnessing "all our government capabilities" and working in close cooperation with governments in the region.

Fort Monroe -- a Union oasis where fugitive slaves flocked during the Civil War -- returns to Virginia's control when the Army pulls out in 2011, and historians are trying to protect the future of the "Freedom Fortress."

Soldiers who need special waivers to get into the Army because of bad behavior go AWOL more often and face more courts-martial. But they also get promoted faster and re-enlist at a higher rate, according to an internal military study obtained by The Associated Press.
